Cate that was my only positive thought about Mac going to London too...that maybe that would be the PTB's way of stopping Peyton...they go to London, something happens...Mac goes home, Peyton stays in London...end of Peyton, happy Mac! I sure as heck hope so...cuz otherwise, heads are rolling...PTB don't even think I'm kidding! Other than that moment with Peyton at the end...this eppy was full of great Smacked moments that made me happy! Them working together seamlessly, saving the lab, saving the world together...being brilliant and all MacGuyver-ish improvising in the lab...that rocked! And I loved how Stell didn't even hesitate to go hug him at the end...nice! Now buh bye Peyton and I'd be happy as a clam!
